car not starting.

[Dr. Winn]

jsut bought a 100$ car. 95 impreza. it wont start. i replaced sparks and wires, fresh fuel filter, cleaned the throttle body, clean the injectors, checked the fuel pump. any ideas on why she wont start?

[C-Fizzy]

Is it not turning over? Can you hear the relay when you turn the key? Maybe a bad starter solenoid

[Dr. Winn]

hmm. let me clarify a bit, it will fire then cut out. like the worlds worst misfire.

[C-Fizzy]

And you've replaced the spark plugs and wires? Checked the distributor cap?

[Dr. Winn]

boxer engine, flat four, dont use a distributor cap. the timing it my next guess tho.

[Autruche]

Bad MAF sensor maybe? are there any leaks in the intake piping? That's the only thing I can really think of, otherwise search for a good subaru forum, you might be able to find a forum just for the impreza, those guys would probably know the exact problem. That's all I got really

[C-Fizzy]

Sorry, haven't done much work on boxer motors, but I say x2 on the subaru forums. You might have better luck there.

[Dr. Winn]

got it to start! but theres no power, i can floor it and its gutless, any ideas? btw there is a strange knocking noise, not rod knock, seems to be comeing from around the intake manifold.

[OrionStang]

You got timing issues. Thats why theres no no power, and the knock is probably the valves staying open and the pistons hitting them. Get the timing right or you'll be buying new heads on a car thats probably not worth it.

EDIT: There could be valve or piston damage already, too, causing power loss.

If its backfiring through the intake that could sound like a knock.

If there is Deisel fuel in the gas that will cause hard starts, poor running and lean backfires. I would get a fuel sample, and double check the spark plug wire order.
